Laboratory Services

Our laboratory is a full service lab which uses state-of-the-art equipment to provide excellent test results.

The WWGH Laboratory is accredited by The Joint Commission and is licensed by the State of Washington. The lab is certified under the Clinical Laboratory Improvement Amendment of 1988 (CLIA) program. Our staff are highly trained and certified, providing you with quick, convenient care.

Lab draw services are available in the main hospital building, and in the main Adventist Health Medical Group clinic building. If fasting is required for your test, please abstain from food or drink (can have water only) for 12 hours prior to testing.

If we are not able to complete your test results in our lab, our relationships with outside reference laboratories allow for completion of the tests in a timely manner. All outside reference laboratories are approved by the medical staff. Please contact the Laboratory at 509-527-8267 if you have any other questions.
